Description
Technical field
The utility model belongs to the physical experiment apparatus field, is specially a kind of Young's modules instrument antichattering system.
Background technology
Young modulus is an important physical parameter of reflection characteristic of material mechanics.Traditional pulling method is measured the metal Young's modules instrument and is adopted the optical lever principle, is subjected to the small elongation under the effect of counterweight pulling force to pass through the specular light lever amplification in tinsel, and by placing telescope and scale at a distance to observe.But in actual mechanical process, the experimenter is difficult for finding the scale picture of being returned by the optical lever flat mirror reflects in telescope, often need to expend the plenty of time and regulate instrument.In addition, telescope has certain distance apart from Young modulus instrument, needs a people at instrument place increase and decrease counterweight in the operating process, and another people observes at the telescope place, perhaps a people runs between instrument and telescope back and forth, thereby can't independently and easily finish experiment measuring.Issued patents number is that 2,010 2 0150310.9 all-in-one laser Young modulus detector adopts laser optical lever to substitute the specular light lever, wiry small elongation after amplifying directly can be read at Young's modules instrument, solved well the problems referred to above.But all there are another problem demanding prompt solution in traditional Young's modules instrument and all-in-one laser Young modulus detector: change in the process of metal wire tension at the increase and decrease counterweight, tinsel shakes easily, causes the reading difficulty and measures inaccurate.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model has been done following improvement to above-mentioned Young's modules instrument by the following technical solutions:
A kind of Young's modules instrument antichattering system comprises weight tray and stop, and described weight tray is disc, the fixedly connected gag lever post in the lower surface center of described weight tray; Described stop is cylindrical, and the center of described stop has one for the through hole of inserting described gag lever post, and described stop places Young's modules instrument base center.
Described gag lever post is rectangular parallelepiped, the rectangular through holes of described through hole for matching with described gag lever post, the height of described gag lever post is less than the degree of depth of described through hole, the length of described gag lever post with wide respectively than length and the wide short 2mm-10mm of described through hole, so that described gag lever post can move by easy on and off in the through hole of described stop.
Described gag lever post is bar magnet, and described weight tray is metal material, and described stop is nonmetallic materials.
The utility model is done less improvement owing to adopt above-mentioned design to traditional Young's modules instrument or all-in-one laser Young modulus detector, can solve tinsel and rock problem, it is simple in structure, and is practical and convenient, with low cost, effect is remarkable, is conducive to improve the accuracy of experiment measuring.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the Young's modules instrument after improving.
Fig. 2 is the schematic perspective view of weight tray of the present utility model and stop.
Among the figure: 1. tinsel, 2. active chuck, 3. base, 4. stop, 5. through hole, 6. weight tray, 7. pallet peg, 8. counterweight, 9. gag lever post.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises weight tray 6 and stop 4, and described weight tray 6 is disc, the fixedly connected gag lever post 9 in the lower surface center of weight tray 6; Described stop 4 is cylindrical, and the center of described stop 4 has one for the through hole 5 of inserting described gag lever post 9, and described stop 4 places the center of Young's modules instrument base 3.
Described gag lever post 9 is rectangular parallelepiped, the rectangular through holes of described through hole 5 for matching with described gag lever post 9, the height of described gag lever post 9 is less than the degree of depth of described through hole 5, the length of gag lever post 9 with wide respectively than length and the wide short 2mm-10mm of described through hole 5, so that described gag lever post 9 can move and avoid back rotation by easy on and off in described through hole 5.
Preferential technical scheme is, described gag lever post 9 is bar magnet, and described weight tray 6 is metal material, and described stop 4 is nonmetallic materials.Only need an end of bar magnet is adsorbed on the lower surface center of weight tray 6 before the experiment, the other end stretches in the through hole 5 of stop 4, regulates the position of stop 4, and gag lever post 9 can be moved by easy on and off in through hole 5, can begin experiment.During experiment, pallet peg 7 is suspended on the bottom of the active chuck 2 of tinsel 1, counterweight 8 be added in weight tray 6 above.
Because stop 4 of the present utility model is positioned at the below of weight tray 6 and contact with tinsel 1 and weight tray 6, so can effectively avoid in the experimentation impact on experimental data.
Gag lever post described in the utility model and through hole also can be other suitable shapes such as triangle, rhombus, and such conversion all drops within the protection domain of the present utility model.
